From the 1973 Code to the BNSS — every stage of a criminal case.

Criminal procedure is the most heavily tested subject in any judiciary exam. Every prosecution moves through fixed stages — FIR, investigation, arrest, remand, charge sheet, framing of charge, trial, judgment, sentence, appeal — and CrPC supplies the procedural rule for each stage. The Bharatiya Nagarik Suraksha Sanhita, 2023, notified on 1 July 2024, retains the architecture and renumbers most provisions, with substantive shifts in time-bound investigation, electronic-evidence rules, and victim rights.

These notes dual-anchor every chapter: the CrPC section and the BNSS counterpart appear on the same opening line. The most-tested provisions — Section 154 (FIR), Section 161 (witness examination), Section 167 (default bail), Section 173 (police report), Section 197 (sanction), Sections 437/438/439 (bail), Section 313 (accused examination), Section 374 (appeal) — are treated section-by-section with the corresponding BNSS provision.

Each chapter is designed to be read in twelve to fifteen minutes and to leave the reader with the dual statutory anchor, the stage in the criminal process, the procedural form, the time limits, the magistrate or court power, and the leading authority.

How to read these notes

01

Start with both citations.

Every chapter opens with the CrPC section and its BNSS counterpart on the same line. Read both. From 2024 onward the prelims paper expects both — a half-remembered CrPC citation without the BNSS pair will lose marks even when the doctrine is right.

02

Place the rule in the criminal-process flow.

Every chapter sits at one of seven stages — FIR, investigation, arrest, charge sheet and cognizance, trial, judgment and sentence, appeal and revision. The scheme paragraph tells you where. A bail rule is solved differently at the FIR stage versus after charge framing, and the procedural posture decides which provision applies.

03

Test on the leading case.

If you can restate the holding of Lalita Kumari v. Govt. of UP, Arnesh Kumar v. State of Bihar, or Hussainara Khatoon v. State of Bihar in two sentences, you understand the chapter. If not, return to the statutory section and rebuild from there.
